Quality Control

Our Uridylyl(2'-5')Adenosine Ammonium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and production. Certificates of Analysis (COA) with detailed chromatographic data are provided to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. Due to its hygroscopic nature, the container should be allowed to equilibrate to room temperature before opening to minimize moisture uptake. For long-term storage, consider desiccant in the secondary packaging.
